Help keep the starter locked out unless the transmission is in Park or Neutral with the Standard Ignition Neutral Safety Switch NS-577. It is a direct-fit replacement for many vehicles, among them the 2008-2012 Honda Accord, 2009-2015 Honda Pilot and 2007-2013 Honda Odyssey. See the Buyer's Guide tab for the full list and engine details.
A neutral safety switch is an electrically operated switch that completes the starting circuit only when the transmission is in Park or Neutral. It is designed to keep the engine from cranking while the vehicle is in gear. If you need a neutral safety switch for a 2009-2015 Honda Pilot or a 2007-2013 Honda Odyssey, NS-577 covers both, along with the other listed Honda and Acura models.
- Built to OE spec: Standard Ignition makes its switches to OE specifications for proper fit, form and function.
- Copper alloy conductors: Provide superior electrical conductivity with low resistive losses.
- Direct-fit replacement: Designed to replace a damaged original unit and return neutral safety function to the starting circuit.
- Robust design: Sturdy construction and high-grade materials suit the demanding needs of today's service professionals.
Signs this switch may need replacing include an engine that won't crank in Park or Neutral, a start that works in only one of those positions, or intermittent no-starts. If a failed neutral safety switch is the cause, NS-577 replaces it. Diagnose the starting circuit first, because other components can produce the same symptoms.
